WORK-HOLDER.

Specification of Letters Patent.

Application fi1ed April 3, 1915. Serial No. 19,013. f

To all whom it may concern 7 Be it known that we, DAVID EDWARD ALLEN and DAVID M. FoRBnss, citizens of the United States, residing at Ardmore, in the county of Carter and State of Oklahoma, haveinvented certain new and useful Improvements in Work-Holders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in work holders and has relation more particularly to a device of this general character especially designed and adapted for use in connection with tire setting machines; and it is an object of our invention to pr0- vide a device of this general character having novel and improved'means whereby a g p g gated holder bar 9, theupper edge thereof wheel may be effectively maintained in applied position and whereby said wheel may be applied to or removed from operative position with convenience and facility.

Furthermore, it is an object of our inven tion to provide a novel and improved work holder which is carried directly by the machine. I

The invention consists in the details of construction and in the combination and arrangement of the several parts of our invention whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fullyset forth.

The novel featuresofthe invention will be carefully defined in the appended claims.

In orderthat our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a View, partly in elevation and partly in section, illustrating a work holder constructed in accordancewith an embodiment of our invention in applied position;

Fig. 2 is a fragmentary elevational view of an elongated member comprised in the present embodiment of our invention; Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1; Fig. 4: is a view in perspective, detached, of the engaging member herein included; and Fig. 5 is a view in perspective, detached, of the straps and their connecting pin as herein set forth.

As disclosed in the accompanying drawings, M denotes a tire setting machine of any ordinary or preferred construction and having projecting upwardly therefrom at Patented July20, 1915;

one side thereof the elongated member-Q1 v provided with the longitudinally disposed elongated slot 2 intersected'by the trans versely alined openings 3 through whicha pin 4 or the like is adapted to "be directed,

for a purpose which will hereinafter be more fully set forth. Also projectingupwardly from the machine is a yoke 5 in alin'ement with the member 1 and positioned ad acent'the opposite side of the bedof the machine and directed through the upper jextremity of said yoke is the removable pi'ni6 serving as a fulcrum for the lever 7,-s aid lever being provided with .a plurality of-lon Disposed through theyoke 5 is an 'elonadjacent its opposite extremities being'pro gitudinally spaced" openings 8 whereby the, leverage thereof may be adjusted'as required."

vided with the recesses or so'ckets'lO, the

socket at the inner extremity of said barbe 'ing adapted to receive the pin 3, hereinbefore referred to, while the secondsocket is adapted to receive the pin '11 disposed through thelower extremities of the straps 12, the opposite extremitiesthereof'being the medium of pivotally engaged through the pin 14' with thelever7. ,v When in applied position, the holder-bar "9 is adapted to extendabovetheffelly of a wheel and is provided with the freely movable engaging member 15 adapted to 'be en- 1 gage'd directly with-{the felly'in a manner and for a purpose whichisbelieved to be self-evident:v As'herein disclosed, said engaging member is substantially U-shape inform and has its stems provided withthe elongated slot 16 through which tlie'holder bar 9 is directed and thebase 17 of said holder member has swiveled thereto the plate 18 which directly-engages the wheel and it will be observed that its swivel connection will serve to "prevent any lateral bend of the bar 9.

The upper edge of the holder bar 9 is provided with the rack 22 which may be 3 integral therewith or separable, as the requirements of practice may dictate, and said rack 22 is adapted to be engaged by the pawl ity of the lever 7.

In order to hold the straps 12 in an inopp 19 pivotally engaged with the inner extrem- Y erative position, we find it of advantage to a provide the lever 7 with a spring catch or clip 20 adapted to be received within an opening 21 produced in one of said straps.

In practice, a wheel is suitably positioned upon the machine M and the holder bar 9 disposed therethrough with one extremity underlying the pin l positioned within certain of the alined openings 3 as the necessities of practice may require. The member 15 is then adjusted upon the bar 9 so that the plate 18 may engage the inner face of the wheel felly. The pin 11 carried by the straps 12 is engaged with a socket 10 of the holder bar 9 and the requisite downward pressure is imparted on the bar 9 through the medium of the lever 7 and the bar 9 is efl'ectively held against retrograde movement through the coaction of the pawl 19 carried by the lever 7 with the rack 22 of the bar 9.

From the foregoing description, it is thought to be obvious that a work holder constructed in accordance with our invention is of an extremely simple and comparatively inexpensive nature and is particularly Well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that our invention is susceptible of some change and modification without material departure from the scope of the appended claims and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice.

We claim:

1. In combination with a work support, a member projecting upwardly therefrom and provided with an elongated slot, a pin intersecting said slot, a yoke projecting upwardly from the support and in alinement with the elongated member, a holder bar disposed through the yoke, one extremity of said bar being provided with a socket to engage the pin of the elongated member, an engaging member slidably engaged with the bar, and means carried by the yoke coacting with the bar for imparting pressure thereto.

2. In combination with a work support, a member projecting upwardly therefrom and provided with an elongated slot, a pin intersecting said slot, a yoke projecting upwardly from the support and in alinement with the elongated member, a holder bar disposed through the yoke, one extremity of said bar being provided with a socket to en gage the pin of the elongated member, an engaging member slidably engaged with the bar, a lever pivotally engaged with the yoke, and a member depending from the lever and engageable with the adjacent extremity of the bar.

3. In combination with a work support, a member projecting upwardly therefrom and provided with an elongated slot, a pin interesecting said slot, a yoke projecting upwardly from the support and in alinement with the elongated member, a holder bar disposed through the yoke, one extremity of said bar being provided with a socket to engage the pin of the elongated member, an engaging member slidably engaged with the bar, a lever pivotally engaged with the yoke, a member depending from the lever and engageable with the adjacent extremitv of the bar, said member being pivotally engaged with the lever, and means carried by the lever coacting with said member for maintaining the same in inoperative position.

4;. In combination with a work support, a member projecting upwardly therefrom and provided with an elongated slot, a pin intersecting said slot, a yoke projecting upwardly from the support and in alinement with the elongated member, a holder bar disposed through the yoke, one extremity of said bar being provided with a socket to engage the pinv of the elongated member, an engaging member slidably engaged with the bar, a lever pivotally engaged with the yoke, a member depending from the lever and engageable with the adjacent extremity of the bar, the upper edge of the bar being provided with a rack, and a pawl carried by the lever engageable with the rack. v

In testimony whereof we hereunto affix our signatures in the presence of two witnesses.
